在Golang中实现动态字符串

Question

I have following global string,

studentName := "Hi ? ,Welcome"

Now I want to take this string dynamically

func returnName(name string) string{
    return studentName+name
}

This function should return string as

Hi name,welcome.

string should take name from parameter,and return dynamic string.What is the best way to implement this in golang.

Answer 1

If you want to keep things simple, you can probably just use fmt.Sprintf.

studentName := fmt.Sprintf("Hi, %s! Welcome.", name)

The %s part will get replaced by the value of name.
